How does Odoo compare to Kantata / Mavenlink / NetSuite OpenAir / Workday Professional Services?

Comparable functional coverage at mid-market scale. Specialist PSA tools have polish advantages in specific areas (advanced resource planning, project forecasting). Odoo wins on unified ERP (no sync between PSA and accounting) and total cost. For mid-market PSA (50–500 employees), Odoo is genuinely sufficient.

Multiple billing methods on one project?

Yes — common pattern. Phase 1 fixed-fee, phase 2 T&M, ongoing retainer for support. Each phase / segment billed per its method. Combined invoicing supported.

Resource planning depth?

Capacity per consultant per role, allocated time per project, conflict detection, what-if scenarios. Not as sophisticated as Kantata for very large global consulting firms with complex skills matching. For mid-market, sufficient.

Multi-currency for international engagements?

Yes — native multi-currency. Consultant cost in their local currency, project billing in client currency, FX gain/loss handled appropriately.

ASC 606 / IFRS 15 revenue recognition?

Yes — percentage of completion, milestone-based, T&M recognition methods native. Deferred revenue waterfall reporting.

Customer portal for project transparency?

Yes — clients see project status, milestones, time logged, invoices, payment status. Reduces project-status inbound queries meaningfully.

Subcontractor / freelancer integration?

Subcontractors granted portal access for time + expense entry. Approval workflow. Cost tagged to project. Common pattern for agencies and IT services using freelancers.

Recurring retainer billing with hour bucket per period, overage handling, bucket rollover rules. Common for ongoing services contracts.

Sales pipeline to project handoff?

CRM opportunity → Sales quote → Sales order → Project automatically. No handoff loss; sales rep sees delivery + collection on opportunity record.

Can we migrate from Kantata / Mavenlink / Workday?

Yes — historical project data, active projects with WIP balances, resource history all migrate. Active projects continue uninterrupted.

What's the implementation cost?

Mid-market professional services (50–200 users): USD 30,000–80,000. Larger firms with complex revenue recognition + multi-currency + multi-entity: USD 55,000–140,000.

What's the first step?

30-minute scoping call. Bring: services type, employee count, monthly project volume, billing model mix, current PSA tool, top operational pains.

Professional Services

Odoo for Professional Services

Professional services firms — consulting, agencies, IT services, accounting practices, law firms, engineering services — run on time and project P&L. Odoo Enterprise unifies sales pipeline, project execution, timesheet capture, project costing, billing (T&M / fixed-price / retainer), and revenue recognition (ASC 606 / IFRS 15) in one database without specialist PSA tool subscriptions.

Pain points & how Odoo solves them

Project P&L visibility is delayed because time, expenses, and materials live in separate tools. Project managers don't know margin until month-end.

Unified Odoo: time + expense + materials + subcontractors all tagged to project in real-time. Project P&L visible to PMs immediately, not month-end.
Multiple billing models per project — some fixed-price, some T&M, some retainer, some milestone — and combining them in invoices is error-prone.

Multi-method billing per project supported. Mixed billing (e.g. fixed-fee phase 1 + T&M phase 2) on same project. Automatic invoice generation per billing rules.
Revenue recognition under ASC 606 / IFRS 15 for project services — when can revenue be recognised, how is it measured, what's deferred?

Native ASC 606 / IFRS 15. Percentage-of-completion, milestone-based, time-and-materials revenue recognition per project. Deferred revenue waterfall reporting.
Sales pipeline lives in CRM, project execution in PM tool, finance in accounting — handoffs lose information and rep can't see delivery status post-sale.

One database. Opportunity in CRM → quote → sales order → project → timesheet → invoice → cash. Sales rep sees delivery + collection status on the same record.
Resource planning is reactive — who's available next week, who's overbooked? Capacity vs demand is in spreadsheets.

Resource planning view in Odoo Project — capacity per consultant per role, allocated time per project, conflict detection, what-if scenarios.
Subcontractor / freelancer time + expense capture is via email + Excel + manual reconciliation.

Subcontractors granted Odoo portal access for time + expense entry. Approval workflow. Cost tagged to project. Pay-when-paid handling if applicable.
Multi-currency engagements for international clients — currency conversion, FX gain/loss, multi-currency billing.

Native multi-currency. Time costs in local currency, billing in client currency, FX rate captured at appropriate stage, FX gain/loss accounted at payment.
